r This invention pertains to plumbing fix-- tures and has more particular reference to a mechanism for controlling the outflow ofwaste or drainage from tubs, sinks, basinsand' other plumbing fixtures or similar receptacles, and to a connection between a plumbing fixture and a water inflow or outflow pipe.

One of the primary objects of the invention is to provide a simple andeconomio'al mecha's nism for controlling the outlet or drainage of waste water etc. from a plumbing fixture or the like and a control mechanism which Will portion within the piping have a minimum system. 7

against which the valvefor controlling the flow through the orificeis adapted to seat and-- also provides a guide or bearing for such valv I Still further objects as well as the advanshould become readily appreciated after reading the following description and claims, and after viewing the drawings, in which:'

looking from the right of Fig. 1, and b Fig. 4 is a front elevation ofthe escutcheon plate and handle of the control mechanism, looking from the left of:Fig. 1. p The plumbing fixture illustrated and desig nated 2 may conveniently be considered to be a'sink provided with an outlet or waste orifice 3 in' its-bottom and an overflow orifice 4 ad j acent its top. The walls of the bottom about the orifice 3 are preferably tapered as shown at 5 so that they converge gradually down ward toward the orifice 3.

In this connection the spud or conj nection element also provides the valve seat distance-thereaboveu- The spud is externall lthreaded,as shown at 9, for engagement with the'threads. 11i of a clampingring or nut12 which'screwsth'ereon and serves to'claimp' the j mm of thelfixture'about the orifice 3 tightly The spud '7 converges downwardly and providedwith'a ground seat 14 against which a valve 15 having a conforming seat 16 is adapted'to seat. The bore 17 of thelower portion of thespud servesas a guide for guide;

ribs 18 formed on the valve 15, whilethe lower part of the exterior of this portion of the spud is threaded, as shown at 19, for threaded engagement with internal threads formed on zon tally idisposed Y; fitting having branches 23and 24, the branch 23 preferably being oval in crossosection with its major aXis ivertically disposed and the branch 24 being of substantially the same shape as the branch 23, but mergingtherewith. The branch 24 is connected with a fitting 25in turn adapted to be coupled to an elbow fitting 26 which connects with a stand pipe or overflow pipe 27 in turn joinedto an overflowfitting 28. The

piping member 21- is connectedwith a waste pipe 29 preferably disposed in ment with the borel'? of the spud.

The boss 31 is provided with a packing gland 34 within which packing 35 is disposed and held in f rod 49. A cap nut 51 prevents theeye48 and place and under compression by a stufing nut 36, while the boss 32 is tightly closed at its lower end by a cap nut 37. The end of the branch 23 is closed by a removable cap 38 for access and inspection.

The reciprocable rod ata portion intermediate the top and bottom inner walls of the branch 23 is secured to a link or connecting member 39 as byithr'eads 4l so' that upon re ciprocation of this rod the'lmember 39 will be moved transversely of thepiping member 21 to raise and lower the valve 15,thereby opening and closing the waste orifice; The' member 39 forthis purpose is provided with a forked end 42 whichembraces a pin 43 thread-z edly connected to the center of the -bottom'of I the valve as by threads 44 and lockedinposition by a lock nut 45. Shoulders 46 and 47 serve to retain the fork and pin in proper relationship. It will now be apparent that as the reciprocable rod 33 is raised and lowered, the valve.15 will be raised: and lowered, respectively. j g. Y

The upper end-of the rod 33, in the embodie ment illustrated, is-bent at right angles to its lowerportion and passes through an eye 48..

secured to a vertically reciprocable operating top portion ofthe rod 33 from relative'dis placement, while a bar 52 secured to; alug 53 integral withthe fitting 26 is spaced adis tance from the-overflow pipesQ/Z and forms.

The eccentric strap is splitfor adjustment andremoval, as shown at 62, the parts being held together by a set screw .63. The:

escutcheon plate 59 and the 'lit'ting '28 are "held tightly against the upper portion-'ofthe fixture about the outlet orifice 4.byi screws 64 which screw into bosses-65 formed internally of and integral with the fitting .28, a gasket rear sideof the fixture about the overflow orifice. It. will be noted that thefitting 28,

while circularaat its end connected with the pipe 27, changes fromsuchshape to arectangular shape at its upper end where it registers with the overflow orifice. The capacity, however,remains substantially the same. It will also be noted that the shaft'1'58 passes through. a boss 60 formedintegral with'the fitting 28 66being placed between the fitting and the.

and does not passthrough-the water channel in the fitting. This arrangement permits the major part of the waste control mechanism, 7

that is, the mechanism for operating the valve, tobe disposed wholly exterior of the overflow and drain pipes,thereby lending to cleanliness, and accessibility while minimizing chances of stoppage of pipes and the chancesof the parts getting out of order.

In order furtherto'minimizethechan ces 'ofthe control mechanism getting out of order and stoppage ofthe waste pipes with debris, "the outlet orifice'is covered with two screens,

a lower screenr67 and an upper screen 68.' The lower'screen was adapted to fit within the tapered, walls just above the orifice 3 and torest-upon and be supported bythe upper end-of the flared lip 8015 the spud? and is": The upper screen 68 is spaced above the lower screen seldom removed in practice.

and preferably is of dish-shape and arranged to contact-with the fixture only about its up,

per circumferential edge e .69 so that it is spaced away-from the fixture between its-bottom and upper edge. Lugs 71' are struckat. two or moreplaces from the sides of the upper screen68 so-that it may be engaged by the fingers orby a tool and readily removed for cleaning or access to lower parts as and when desired. r I a t Though T-l aveillustrated and describeda preferred, embodiment of the invention, it
